Photocatalytic oxidation of methyl ethyl ketones over sol-gel mesoporous and meso-structured TiO2 films obtained by EISA method
This work reports the influence of the meso-structure of TiO2 films in the photocatalytic oxidation of methyl ethyl ketone.
TiO2 thin films for the photodegradation of TCE in air: Optimization of the sol-gel preparation method
Porous TiO2-anatase thin films were prepared by the sol–gel route and used for the study of the influence of structural properties in their photocatalytic activity.
Rolling-sliding, scuffing and tribocorrosion behaviour of PVD multilayer coatings for gears application
In the past decade, the emerging new class of nanoscale multilayer coatings has offered to the materials scientists a powerful toolbox for the engineering of the design of PVD coatings through a combination of the multilayer concept with new nano-structured coatings (Román, 1993; Kok, 2005).
Alternative Cr+6-free coatings sliding against NBR elastomer
Hexavalent chromium compounds result attractive primarily for industrial activity because they provide manufactured products with enhanced hardness, shininess, durability, color, corrosion resistance, heat resistance, decay resistance and tribological properties.
Performance and Behavior of Seals for Pneumatic Spool Valves
This article presents a seal development approach that takes actual operating conditions (mounting, sealed pressure, lubricating conditions), seal material, and counterpart machining tolerances into account.
Zirconium-based coatings in highly stressed rolling contacts as alternative solution to DLC and ta-C coatings
The slip-rolling resistance of DLC, a-C and ta-C thin film coatings was improved considerably in the last years, but there is still room for improvements in relation to (a) the temperature stability and (b) initial surface roughness after deposition.
